Quick Answer
Yes, there are federal regulations governing the power output of CB radios in the United States. The Federal Communications Commission (FCC) limits CB radio power output to 4 watts on the 11-meter band. Exceeding this limit can result in fines and penalties.
CB Radio Power Output Regulations
The FCC regulates the power output of CB radios in the United States to prevent interference with other radio services and to ensure compliance with international agreements. The 11-meter band, which is the frequency range used by CB radios (26.965 MHz to 27.235 MHz), is allocated for commercial and amateur use. The maximum allowed power output is 4 watts, which is specified in the FCC’s rules and regulations (47 CFR 95.635).
CB Radio Power Measuring Techniques
To ensure compliance with FCC regulations, CB radio manufacturers and users must be able to measure the power output of their devices. The FCC specifies the use of a peak envelope power (PEP) measurement method, which measures the maximum power output of the radio during a single transmission cycle. Users can measure the power output of their CB radio using a calibrated wattmeter or a spectrum analyzer. It’s essential to calibrate the measurement device regularly to ensure accuracy.
Penalties for Exceeding CB Radio Power Output Limits
Exceeding the allowed power output limit for CB radios can result in significant penalties, including fines and equipment confiscation. The FCC takes enforcement action against CB radio users who exceed the power output limit, and individuals found guilty of violating the regulations can face fines of up to $11,000 for each offense. In addition, the FCC may confiscate equipment that is used to exceed the power output limit.
